Description

本考案は、座姿勢における腰部への負担軽減を実現し、一人で柔軟運動やストレッチ運動を行うことができる機能を備えた座椅子の構造に関するものである。   The present invention relates to a structure of a seat chair that has a function of reducing a burden on a waist portion in a sitting posture and capable of performing flexible exercise and stretching exercise by one person.

従来の座椅子は「座って楽」ということを主な目的とし、休息時には、より身体が楽になるようにと、仰臥姿勢又は横臥姿勢が可能なもの、あるいはマッサージ機能が付いたもの等があったが、いずれも座椅子の使用者を静的に捉えていた。   Traditional seat chairs are mainly intended to be “sit and comfort”, and when resting, there are those that can be in a supine or lying position, or those that have a massage function, etc. All of them were static about the seat user.

一方、座椅子の使用者を動的に捉えたものとしては、屈伸運動や腹筋運動を一人で可能とするものがあったが、出来る運動が限られることや、座り直しが必要であるなど、機能的に制約を伴うものであった。また、運動機能を有する従来の座椅子は、運動時の機能を重要視するあまり、通常の座姿勢の際の腰部に対する負担軽減については、おろそかになりがちであった(特許文献1、2参照)。   On the other hand, the one that dynamically captured the user of the sitting chair was one that allowed flexion and extension exercises and abdominal muscle exercises alone, but the exercises that can be done are limited and it is necessary to sit back It was functionally constrained. In addition, conventional seat chairs having motor functions tend to be neglected in reducing the burden on the waist during normal sitting postures because the functions during exercise are regarded as important (Patent Documents 1 and 2). reference).

以下、本考案の座椅子の一実施態様を、図面に基づいて具体的に説明する。なお、本考案はこれら実施態様に何ら制約されるものではない。   Hereinafter, one embodiment of the seat chair of the present invention will be specifically described with reference to the drawings. Note that the present invention is not limited to these embodiments.

図1は本考案に係る座椅子の後方からの斜視図である。図中、1は座部、2は腰当部、3は支柱、4は転倒防止突起、11は座面、Xは座面より腰当部の上面までの距離をそれぞれ示す。   FIG. 1 is a perspective view from the rear of a seating chair according to the present invention. In the figure, 1 is a seat part, 2 is a waist support part, 3 is a support | pillar, 4 is a fall prevention protrusion, 11 is a seat surface, X shows the distance from the seat surface to the upper surface of the waist support part.

図1に示すように、本考案に係る座椅子は、略矩形の座部1と、その座部1の後部から立設された支柱3と、その支柱3の上部に取り付けられた腰当部2とからなる。腰当部2は支柱3の左右に突出するよう設けられている。腰当部2は、座姿勢において腰部を適切に支持するとともに、運動時にはこの腰当部2を掴んで押すあるいは引くことにより、体の特定の部位にかける負荷を調整することができる。さらに、支柱3の下部には、転倒防止突起4が後方に突出して設けられている。このように、転倒防止突起4が後方に突出していることにより、運動時に腰当部2に体重をかけた場合に座椅子が後方に転倒することを防止することができる。   As shown in FIG. 1, a seat chair according to the present invention includes a substantially rectangular seat portion 1, a support column 3 erected from the rear portion of the seat portion 1, and a waist pad attached to the upper portion of the support column 3. Part 2. The waist contact portion 2 is provided so as to protrude to the left and right of the column 3. The waist support part 2 can appropriately support the waist part in the sitting posture, and can adjust the load applied to a specific part of the body by grasping and pushing or pulling the waist support part 2 during exercise. Further, a fall prevention protrusion 4 is provided at the lower part of the column 3 so as to protrude rearward. Thus, the fall prevention protrusion 4 protrudes rearward, so that it is possible to prevent the seat chair from falling backward when the weight is applied to the waist rest part 2 during exercise.

座面11より腰当部2の上面までの距離Xは任意であるが、座姿勢における腰部への負担軽減や、後述する各種運動の効果を十分に引き出すためには、その範囲を18cmないし25cmとすることが望ましい。また、腰当部2の幅については、同様の理由により、45cm以下とすることが望ましい。   The distance X from the seating surface 11 to the upper surface of the waist contacting part 2 is arbitrary, but in order to reduce the burden on the waist part in the sitting posture and to fully bring out the effects of various exercises described later, the range is 18 cm to 25 cm. Is desirable. Moreover, it is desirable for the width | variety of the waist contact part 2 to be 45 cm or less for the same reason.

図2は、本考案に係る座椅子の骨組みを表した斜視図である。図中、12は座部フレーム、31は支柱フレーム、32は枢設部、41は転倒防止突起骨部をそれぞれ示す。本考案に係る座椅子は、その基本的な骨組みをスチール製のパイプおよびプレートからなるフレームで構成し、かかる骨組みの上から、ウレタンなどの弾力性を有するカバー生地を被せて使用する。   FIG. 2 is a perspective view showing the framework of the seat chair according to the present invention. In the figure, reference numeral 12 denotes a seat frame, 31 denotes a support frame, 32 denotes a pivoting portion, and 41 denotes a fall-preventing projection bone. The seat chair according to the present invention comprises a basic frame composed of a frame made of steel pipes and plates, and is used by covering the frame with a cover fabric having elasticity such as urethane.

本実施態様の支柱フレーム31は、座部フレーム12に対し、枢設部32を介して角度を調整できるよう枢設されている。かかる角度は任意に設定可能であるが、本実施態様のものは、収納時に支柱フレーム31を後方に倒して座部フレーム12に対し平行方向に伸ばすことが可能となっており、よって、支柱3は座部1に対しておよそ90度ないし180度の範囲で調整可能となっている。   The support frame 31 of this embodiment is pivoted with respect to the seat frame 12 so that the angle can be adjusted via the pivot 32. Such an angle can be arbitrarily set. However, in the present embodiment, the support frame 31 can be tilted rearward and extended in the parallel direction with respect to the seat frame 12 during storage. Is adjustable with respect to the seat portion 1 within a range of approximately 90 to 180 degrees.

次に、本考案に係る座椅子の具体的な使用方法について説明する。図3ないし図5は、本考案に係る座椅子を使用した座姿勢の態様を表した図である。図3のように本発明の座椅子に深く座った場合、使用者の骨盤上部から腰椎の下部辺りが、座椅子の腰当部2に寄り掛り、支えられているが、この姿勢から使用者が上半身を後傾すると、その上半身は腰当部2に乗り掛る状態となる。すなわち、本座椅子の使用者は、深い座り姿勢の時に、上半身を後傾して座椅子の腰当部に乗り掛ることで腰部に加わる負荷を中断したり、軽減したり出来る。   Next, a specific method of using the seat chair according to the present invention will be described. FIG. 3 to FIG. 5 are views showing the form of the sitting posture using the sitting chair according to the present invention. When sitting deeply in the seat chair of the present invention as shown in FIG. 3, the lower part of the lumbar vertebra leans against the waist contact part 2 of the seat chair from the upper part of the user's pelvis, but from this posture, When the user tilts the upper body backward, the upper body gets into a state where the user sits on the waist portion 2. That is, the user of the seat chair can interrupt or reduce the load applied to the waist portion by leaning the upper body backward and riding on the waist rest portion of the seat chair in a deep sitting posture.

また、図4のように浅く座った姿勢では、上半身は座椅子の腰当部3に乗り掛っているので腰への負荷は小さい。さらに腰当部3は力学的に支点となっているので臀部の滑りもなく、また、上半身の反りだけではなく腹圧の調整でも、腰部に加わる負荷のコントロールが出来る。   Further, in the posture of sitting down shallowly as shown in FIG. 4, the load on the waist is small because the upper body rides on the waist abutment portion 3 of the sitting chair. Furthermore, since the waist support part 3 is a fulcrum, the hips can be prevented from slipping, and the load applied to the waist can be controlled not only by the warping of the upper body but also by adjusting the abdominal pressure.

本考案に係る座椅子を使った正座では、一般の正座や正座用椅子による正座と異なり、図5のような臀部を後方斜め下から支え、臀部が踵に若干触れる程度の正座姿勢を可能とする。この正座姿勢は骨盤が立ち易いだけでなく背筋も伸び、又股関節の可動による重心移動が全方向に行ない易いので、腰椎の椎間板の特定部位に負荷が加わり続かないようにコントロール出来る。   In the sitting position using the seating chair according to the present invention, unlike the sitting position of a general sitting seat or a sitting chair, the sitting position as shown in FIG. And In this orthopedic posture, not only the pelvis is easy to stand but also the back muscles are stretched, and the center of gravity can be moved in all directions by moving the hip joint, so that it is possible to control so that a load is not continuously applied to a specific part of the lumbar intervertebral disc.

次に、本考案に係る座椅子を使用した運動の具体例について、図6ないし図9により説明する。本発明の座椅子による伸身の前屈では、図6のように、脚を伸ばして深く座った姿勢から両手で座椅子の腰当部を掴み、胸を開いて腰を伸ばし、骨盤が立って臀部が浮きぎみになるように腕に力を入れる。そして、股関節のみ曲げる意識で座椅子の腰当部2を後方に押し、さらに両腕が背中に覆い被さり、胸椎が曲がらないように両肘を伸ばしていく(図7)。以上のような股関節の柔軟性を高めるための伸身の前屈運動では、股関節への意識を明確にし、先に曲がり易い腰椎や胸椎を伸ばしておくことで股関節に効率的に負荷を与え、かつ座椅子の腰当部を後方に押すことでパートナー無しでも強い負荷を加えることが可能となる。このような前屈運動は他の座姿勢、例えば図8のような開脚、足裏を合わせた座姿勢、また片膝を立てた座姿勢であっても、同じ要領で効率的な強い負荷を加えることが出来る。   Next, a specific example of exercise using the seat chair according to the present invention will be described with reference to FIGS. In the forward flexion of the body by the seat chair of the present invention, as shown in FIG. 6, from the posture of sitting deeply with the legs extended, grasping the waist portion of the seat chair with both hands, opening the chest and stretching the waist, Stand up and put your strength into your arms so that your hips are floating. Then, with the consciousness of bending only the hip joint, push the waist portion 2 of the seat back, cover both arms over the back, and extend both elbows so that the thoracic vertebra does not bend (FIG. 7). In the forward flexion movement of the body to increase the flexibility of the hip joint as described above, consciousness of the hip joint is clarified, the lumbar vertebrae and the thoracic vertebrae that can be bent first are stretched, and the hip joint is efficiently loaded. In addition, it is possible to apply a strong load without a partner by pushing the waist portion of the seat chair backward. Such forward bending movements can be applied to other seating postures, for example, open legs as shown in Fig. 8, seating postures with the soles in contact, and sitting postures with one knee up. Can be added.

さらに、図9のように、左腕は出来るだけ鎖骨の延長線上になるように伸ばし、左肘と左膝を合わせ、左臀部の内転により左膝で押し、左側腹部を伸ばしながら左上半身を強く捻る。また、座椅子の腰当部2の上に置いた腕に乗り掛り、右側腹部を伸ばしながら上半身の右側腹部がより捻じれるように右腕に力を入れる。これらの運動は骨盤を固定した状態で左右の側腹部を伸ばしながら両腕と片方の脚の力を十分に加える事が出来るので効率的な強い捻りを生むことが出来る。さらにこの運動は、側腹部のストレッチや肋骨・肩甲骨・肩関節の可動性を高める効果もある。このように、本考案に係る座椅子を使って上半身を捻る運動もいろいろな座姿勢からできるが、骨盤を固定する事により効率的に負荷を加えることができ、かつ座椅子の腰当部を押したり、引いたりすることにより大きな力を加えることができる。   Furthermore, as shown in Fig. 9, the left arm is extended as much as possible on the extension line of the clavicle, and the left elbow and the left knee are aligned. twist. In addition, the user puts on the arm placed on the waist-rest part 2 of the seat, and puts power on the right arm so that the right abdomen of the upper body is twisted more while stretching the right abdomen. Since these exercises can apply the force of both arms and one leg while stretching the left and right flank with the pelvis fixed, an efficient strong twist can be produced. Furthermore, this exercise also has the effect of increasing the mobility of the flank, ribs, scapula, and shoulder joints. In this way, the seat body according to the present invention can be used to twist the upper body from various seating postures, but the load can be applied efficiently by fixing the pelvis, and the waist of the seat A large force can be applied by pushing or pulling the part.
